In scientific research , scientific validation is an essential part of physical experiments by the constraints of the experimental conditions , a lot of manpower and material resources , and even endanger the personal safety of laboratory personnel , with the development of computer technology , computer simulation has become a scientific a necessary means of verification , the emergence of virtual reality technology to make the simulation more intuitive and better human-computer interaction , can be more effective verification , visual simulation as a virtual reality simulation is an important branch of the results of scientific research , research in recent years has become a hot spots. Virtual reality simulation in the field of ship control , the majority of semi-physical simulation or graphics workstation as the center of the visual simulation system simulation fleet built , the high cost of research , institution or organization for the lack of research funding research in this area is difficult to , limiting the popularity of virtual reality technology and marketing . The personal computer hardware to the ship's track / heading control system for the object , using virtual reality technology to build a visual simulation system , the control algorithm and three-dimensional view of organic combination ; using Matlab and the the VisualC mixed programming , achieve a digital simulation and visualization of simulation unity ; online computing algorithm programming mode , online simulation ship encountered a variety of situations at sea sports . Details are as follows : First, the selected motion model of the ship , steering gear , Vessel's Track controller and heading controller mathematical model and mathematical model of interference . Secondly, the use of numerical integration of Runge-Kutta method , using Matlab Digital Simulation of pre - established mathematical model for on-line operation . Again using MultiGen Creator and Vega simulate the real environment the virtual reality environment modeling, visual simulation system to build a three - dimensional virtual scene . Finally, Visual C development environment , the use of a COM-based Matlab and VC mixed programming is used to control the operation of the algorithm , Vega API virtual scene compilation , visual simulation and digital simulation of organic integration , and digital simulation curve the movement of the 3D scene elements synchronized show in the ship track / heading control visual simulation system .
